Four Considerations when Choosing your Swimming Pool Deck Drain

When faced with the prospect of selecting a channel drain for your swimming pool deck, your task can seem overwhelming.  Your contractor may only have a handful of the drain products available in his regional marketplace.  Additionally, if you are looking for custom or design-specific grating options, you may have to spend many nights researching on your own for a product that is just right.  A deck drain consultant can be a big time saver.

Pool deck drain selection is a balancing act between deck design, functionality, aesthetics, safety and cost.  It is important that the pool owner weigh the relative value that each of these features have to his project prior to designing the pool drain.

1. Budget Considerations

Is cost the overall driving factor in your selection?  Or, would you consider a drain with a little something extra to act as a conversation piece?  In the pool drain world, there is a broad spectrum of product costs.  The standard 1.5″ wide deck drains, which inevitably get clogged and break, are at the bottom of the spectrum.  From there, systems are available in all cost ranges, up to 10 times the cost of the low end product.  I should point out that quality systems are available at affordable prices for those watching the budget.  In general, pre-sloped systems are more expensive than neutral (non-sloped) systems.  However, pre-sloped systems have installation advantages that we will point out below.

2.  Functionality Considerations

When I start discussing a pool deck drain with a client I ask them, “How is the pool deck to be constructed?”   Is the deck made of poured concrete, pavers, or tile?  All drains can be installed in a concrete deck construction, but not all drains work well with paver stone or tile.   Drainage systems that are designed with straight walls provide a linear surface that are great for laying paving stones against.  If the drain body has legs or support structure that are too close to the top edge of the channel, abutment of pavers will be compromised.

Examples of this are shown below.  Mini Channel and Polycast are both systems with straight walls and play well with paving stone.  Dura Slope and Pro-series #5 have rebar connection features that make it impossible for pavers to lay adjacent.  These latter products need to be encased in concrete prior to laying the paving stone.  In streetscape applications, this may be a reasonable design approach.

3.  Drain Capacity

Wrapped in this conversation we should begin to consider how large of a drain we need for the deck application.  How large is the project and how much water is the drain required to handle?  Is this an Olympic sized pool or are we looking at a back yard sauna?  Long drains generally need to have a pre-sloped channel body if you plan to have only one drain outlet.  Neutral drain bodies, like NDS Mini Channel, can be used in long or complex drain designs as long as they are designed with bottom outlets every 15 – 20 feet.  This requires a parallel plumbing design running beneath the deck drain.  Though a little more complex in the construction, frequent bottom outlets gives you design flexibility that you can’t get with some wider, higher volume deck drain systems.

4.  Aesthetic and Safety Considerations

Once a deck drain is installed in your pool, the only evidence you have is the top grate – or grille, as some call it.  The selection of the grate will determine how much attention is brought to the drain and how safe the grate will be to pool goers.  My first “Rule of Thumb” is to make deck drain grates “barefoot friendly”.  The openings should be small enough to prevent a toe from getting caught in it.  This is not always possible if you have some really inquisitive children, however.

brass pool drains, decorative pool drains,

Decorative grates bring an added touch of elegance to the pool deck, but need to be selected with safety in mind.   Cast iron metal grating not only can rust and become unsightly but have a high heat capacity that are hot to the touch during summer months.  Plastic, aluminum and bronze grates seem to be a more popular grating choice for deck drains in high foot traffic areas.

Grating color is another aesthetic parameter that comes into play.  Grates made from plastic, metal and stone are all available in a varieties of color.  White, tan and light grey are the three most popular deck drain colors.  Darker grey grates are used in bluestone and some paver pool deck designs.  Brass, bronze, stainless steel, cast iron and aluminum grates are popular in modern, designer pools.

Where to do research…..

After you have a drain design roughed out, visit www.DrainageKits.com and see some of the options available in kit form for pool applications.  Look through all the drain options, not just pool and patio drains.  You will be able to see options and pricing.  While doing this research, you will begin to narrow down exactly what it is you want.  If you still need to discuss the project, contact one of the drain professionals at Trench Drain Systems at 610-638-1221.  They can offer more direction to your search and help with the project estimate.

New “Cathedral” Grating for NDS Mini Channel

Trench Drain Systems expanded its decorative offering for NDS Mini Channel with a new pattern of bronze and aluminum grating. The design, borrowed from Chester Cathedral in Chester, England, (shown below) is heel-proof, subdued and stylish.   It adds a solemn aesthetic to the hardscape and hints of a yearning for the innocence of old.

Chester Cathedral, previously Saint Werburgh’s Benedictine Abbey, was built in the 10th century on the site of a church founded in part by the infamous Lady Godiva.  The grating shown below was probably installed during a major rebuilding that occurred in the 1900s.

Mini Channel Grating Expose’

Mini Channel is a popular 3 inch wide profile channel drain manufactured by NDS.  It is produced in Fresno, CA and stored in one of the four company warehouses and multiple distributors across America.  It is arguably the most versatile channel drain in its class on the market today.  Here’s why:

  1. nds mini channel, mini channel, plastic channel drain, plastic pvc drain,
    Mini Channel Extrusion Process

    The extruded, PVC cell-core construction of Mini Channel makes it inexpensive while also sturdy enough for popular residential applications, including pool decks and patios.

  2. The 3″ wide and 3″ depth dimension makes it large enough to handle most patio run-off scenarios while still being small enough to be inconspicuous.
  3. The straight wall construction of Mini Channel makes it compatible for most paver projects, while also being great in poured concrete decks.
  4. The grating selection of Mini Channel is one of the largest in the industry.  At last count, this mighty channel boasts of over 30 different grating options (All available at Trench Drain Systems)

Currently, there are four companies that produce grating products for the Mini Channel.  The color, material and design options are widespread making this system virtually perfect for any home decking or patio project.  Check out the selection below.

NDS

plastic drain grates, 2.75 grates, 3in plastic grates, nds channel grates,Of course, the manufacturer of Mini Channel will have some grates to use with their system.  They originally began with a six color plastic slotted grate offering and two brass grates (polished and brushed).  After competition in the marketplace proved that decorative grating was a viable option, NDS developed two decorative patterns of their own: “Wave” and “Botanical.” They began offering these two patterns in four colors (plastic) and in cast iron.  In all, NDS has 18 different grate selections for the Mini Channel.

“Raindrop” (top) and “Slotted”

The most recent contributor to the Mini Channel grating selection is Trench Drain Systems.  Their contribution has been centered on providing simple, time tested, patterns in bronze and powder coated aluminum.  Currently, the patterns they offer are slotted and raindrop.  The bronze selections are sturdier than the NDS brass grates, having 50% more mass and capable of higher loads.  Bronze grates are available with a natural and brushed finish.

The bronze grate selections are sturdier than those offered by NDS for two reasons.  First, bronze is structurally a stronger material than brass.  And second, the grating offered by TDS have 50% more mass.  In comparison to the NDS product, they are heavier, sturdier and capable of higher loads.

nds mini channel grates, aluminum mini channel grates, 3in aluminum gratesLikewise, TDS makes the aluminum grates available in the same two patterns but with the added feature of being powder coated.  The color choices are Caramel Beige, Textured White and Granite Grey.  The coated aluminum grates are popular around custom pools.  The aluminum grate won’t rust, as will the cast iron grates.  Also, the aluminum isn’t susceptible to deterioration in UV light and won’t break when the foot of a chair is placed on it.  Forget about needing to replace your plastic pool grates every third season.  For large projects, custom powder coatings are available for an added cost.

Iron Age Designs

Iron Age Designs popularized the idea of making decorative grates for the standard, off-the-shelf drains like Mini Channel.  In fact, their “Minione” cast iron grate was the first of 5 decorative grate patterns made for the Mini Channel system.  They also offer their decorative products with a baked on oil finish.  Iron Age’s success in capturing a portion of NDS’s trench drain grate market led to the development of the previously mentioned NDS deco grating products.

Though not a newcomer to the drainage market, Jonite USA is new to the Mini Channel band wagon.  They manufacture a unique material, called Jonite, which is made from the re-constitution of ground granites and other natural stones.  The product is reinforced during the forming process to meet the engineered property requirements of the application.  Their Baby Pebble (shown here) and Interlace patterns are available in Desert Beige and Charcoal Black.  The grates are made to ride on top of the Mini Channel and are meant to be used in paver applications.  The thickness of the grate extends far beyond the top edge of the Mini channel.  The paving stone is installed just flush with the top of the channel/grate combination.

As this is a new company to the US Market, they haven’t quite gotten their distributorship established.  Nothing is stocked in the United States as of print.  Lead time on an order is about 4 months, as it will be coming to you on a boat from Singapore.

NDS Revamps 5 inch Pro Series

buy plastic grates online, buy plastic grates, buy nds drains online, 5 inch pro series buy now

In 2012, NDS rolled out an improved channel for the 5 inch Pro Series. The 5 inch Pro Series is the workhorse of the Pro Series line, which ranges from 3” – 12” wide. The 5 inch Pro Series is sold in hardware stores around the country, though only in kit form. If you want to buy special grates or additional components, you’ll need to find an online store.

Rebar Connection

The first striking difference between the new and old design is the rebar attachment feature. (See below.) In the original rebar attachment design, a hole in the channel’s supporting foot allowed the installer to thread a piece of construction wire to connect rebar. The new rebar attachment design features a plastic clip that affixes to a No. 4 rebar (1/2”) without a tie wire.

Enhance Ribbing

The new 5 inch Pro Series model also sports a new rib design. The ribbing was originally designed into the system to define the location where the channel could be cut during final channel length adjustment. Compared above, one can see how one of the ribs in each pair has been extended. The extended rib has three purposes.

  1. It acts as a guide to assist in manual trimming of the channel,
  2. It gives more rigidity to the channel body, and
  3. It is part of a new, snap-fit tongue-and-groove channel connection design.

5 inch Pro Series channel drain, 5 in plastic drain,

There is a fourth purpose of the rib re-design, shown above. Three of the extended ribs have pedestal extensions, which are great for leveling the channel during installation on a tamped gravel surface. In the previous 5 inch Pro-Series design, the bottom outlet prevented the channel from setting level on a flat surface. The new design eliminates this issue to improve the overall installation experience.

Improved Channel Connection

Probably the best outcome of the 5 inch Pro Series redesign is the new channel connection snap fit. Above, one can see both designs are still a tongue and groove fitting. The big difference is in the small “snap housing” at the top of the new design (left channel). Upon completion of the tongue and groove connection, a tab on the male end of the channel makes a “snap fit” with this housing and secures the assembly.

With the previous design, PVC glue was used to secure the channel connection. Though, PVC glue would make the joint between the two channels water tight, it’ application was sometimes an afterthought and made for a more complicated installation.

 Different Plastic Composition

You may have noticed a slight color difference between the two channels in comparisons above. That’s because NDS altered the plastic composition of the channels. The early version was made of a Poly Vinyl Chloride (PVC) composition while the new channel is made from Poly Ester (PE). The grates used in the system have not changed. They are still as reliable as they were in the past.

There are property differences between the two plastics. However, these differences may be more significant to the manufacturer than the customer. Two helpful observations I’ve made between the two plastics:

  1. You can’t use PVC Glue to connect your new 5 inch Pro Series channels. It doesn’t work. You’ll have to find another product other than “good ol’” PVC glue. I initially learned of the new channel design from an irate customer complaining that he couldn’t glue these new channels together. At that point, NDS still had an old installation data sheet circulating. Oops!!
  2. If you freeze and drop PVC components, they will crack. I learned this after receiving a January shipment of NDS PVC catch basins. The product arrived in the box shattered due to poor handling by the trucking company. If it was July, they probably wouldn’t have been broken.

Channel Weight

The final difference between the two 5 inch Pro Series designs is the channel weight. The new channel weighs 15 percent less than the previous channel. This may be due to the actual density of the plastic itself. Or, it could be related to some reduced channel dimensions. My gut feeling is that the weight change is an inherent property of the plastic rather than reducing the amount of plastic in the design. In fact, with the added features of the new design, it seems that NDS has “beefed up” on the volume of this channel. Again, this is my gut feeling and not based on any technical evidence.

NDS’s design change to the 5 inch Pro-Series hasn’t changed the width or length, but new design features make installation easier. Some installation problems may crop up if one is trying to make a construction blending the two designs.

I’ll miss the old design because we spent so many years together. However, I look forward to working with this new channel. Good job NDS, Inc.!!!

Mini Channel Plastic Grates are Prettier, Sturdier than Ever!

Mini Channel, the 3” plastic channel drain that has long been one of NDS’ most popular systems, now offers slotted plastic grates with a smoother, more decorative appeal.

New mold die (top) next to old plastic grate (bottom)

NDS overhauled the design of slotted Mini Channel plastic grates following the release of decorative plastic grating for the 3” channel drain in 2013.

The new design eliminates hard edges and flashing made when using the old injection mold die. The new die gives the grates a smoother look and the Mini Channel system a cleaner appearance.

The new Mini Channel grate pattern isn’t just for appearance’s sake, either. The new mold lengthens the plastic grate’s supporting ribs, which run perpendicular to the trench’s length (think hamburger, not hot dog). Supporting ribs increase a grate’s longevity under traffic and serve to make the plastic channel grate sturdier. The better a grate’s support structure, the less vehicle stress will affect it.

While the updated look on the Mini Channel won’t increase the channel drain’s overall load bearing capacity, it does make the grate more rigid.

It is important to point out that this improvement didn’t increase the cost of the Mini channel grating.  For an estimate on a Mini Channel system for your patio application, request pricing from one of the specialists at Trench Drain Systems today.

Decorative Plastic Trench Grates Exist!

Ever since the first line of plastic trench drains emerged on the market, homeowners have welcomed the convenience of lightweight, affordable drainage systems. Easily purchased and installed, plastic drains bring patio and driveway drainage systems to an accessible level.

But a lingering flaw in plastic drainage systems has been the same simplicity that made them popular. The smallest plastic drains are about 1.5” wide and, though they come in up to three colors (usually gray, sand or white), are just narrow strip drains with no ornamental grating options. Larger drains between 2” – 4” wide come standard with plastic slotted grates that offered new colors but no design improvements.

Now NDS’ design efforts allow anyone to buy decorative plastic trench grates for new and preexisting NDS drain systems. The new Botanical and Wave designs are both beautiful. (see a side by side comparison below). While the pattern options are still developing, both styles come in trademark NDS colors of sand, black, green and gray.

These grates are available for the 3” Mini Channel and the 4” Spee-D Channel systems, and they also work with 12” catch basins. Overall, I think the new decorative grates improve the 3” and 4” NDS profile drains. Let me show you why.

NDS Mini Channel plastic drain system

The Mini Channel and Spee-D Channel profile drains feature honeycomb chambers within the wall. Spee-D Channel drains (not shown here) have thicker walls to accommodate their greater width, but the basic construction is the same. Profile drain grates rest on a lip in the channel body and are screwed into place.

Mini Channel with Botanical grate (left), with Gray Slotted Grate (right).

Traditionally, either system’s slotted plastic grates rest fully within the channel and do not hide its edge (see above photo, right). Gray channel edges are visible on either side of plastic slotted Mini Channel or Spee-D Channel grates, a detail frequently commented on in upscale applications.

“[The visible channel border] has been a long running criticism of the Mini Channel and Spee-D Channel,” says Mike Schreiber, District Sales Manager at NDS.

Personally, I always felt this was a design flaw on the part of NDS not only because water can gather between the grate and the channel but also because it’s not aesthetically appealing. I’m pleased that NDS is taking steps to improve on the design.

NDS’ decorative grating (see above photo, left) is thicker. The grates hang over the channel walls. Once installed, all you see of the drainage system on the left is the Botanical pattern grate.

The photo above shows how nicely the new decorative plastic grates fit into NDS profile drains. I do like these grates better because their added thickness makes the systems more durable. It also makes the grates sit higher in the channel, which means you’ll have to use special screws to secure the grates.

At first I was concerned that the additional height would tempt the Fates and lead to broken drains. However, NDS specifications recommend profile channels be recessed up to a quarter inch to improve drainage. Recessed drains also protect the channel from snow plows, which have been known to tear up grates. If there are any issues they will probably occur in preexisting drains that were not installed in a recess. But if the existing drains were installed properly there shouldn’t be a problem.

When decorative cast iron grates became a reality for homeowners, plastic drain manufacturers realized they were missing out on a large market. Contractors and homeowners saw cast iron grates as an upgrade to basic slotted plastic worth the extra cost, but decorative plastic was unsold real estate in the trench drain market. So far, only NDS has done anything to fill the market need.

Seeing an unmet market need, NDS began developing their line of decorative plastic grates a year ago. The manufacturer conducted surveys among customers and contractors to help choose which designs would be most popular before sending out small batches for trial runs. The end result is that homeowners can now buy Botanical and Wave pattern plastic grates for their profile drains and catch basins.

The decorative grates are making in-roads on applications where drainage systems are visible such as commercial pools, patios and sidewalks. While they aren’t driving new sales – nobody who doesn’t need a trench drain is buying the grates just to have them – homeowners and contractors lean toward decorative plastic because of its improved aesthetics.

“I’m really starting to see the decorative channel take off,” Schreiber says.

Many NDS drains have a decorative iron option available (see our blog about decorative cast iron grating here). Plastic decorative patterns are still limited at the moment, but I expect options to expand once the idea of affordable plastic replacement grates sinks into the public’s mind. NDS, now busy incorporating new acquisitions such as KBI flow control and ADS drainage systems, is going to wait before expanding their decorative offerings.

Patio and Driveway Drainage Solutions Part II – New Catch Basin Drain Grate Options

We left off our previous blog after after introducing standard grating options such as the plastic slotted grate and the painted black iron grate.  The neat thing, though, is that multiple grates fit the 12″ x 12″ size profile adapters and catch basins.

Three new grating options recently became available to the market, which open up the design possibilities for every budget. Now there are designer grates available in plastic, cast iron and reinforced stone.

Designer Plastic Grates by NDS

Earlier this year, NDS came out with two new grating designs that are expected to replace the standard plastic slotted catch basin grate. Their Wave (left) and Botanical patterns (right) come in four colors and fit the 12” x 12” catch basins and low profile adapter for both NDS and ADS products. They are interchangeable. The price of these designer grates are a few dollars more than the standard slotted plastic grates. This allows for the affordable replacement of existing basin grates.

Decorative Cast Iron Grates by Iron Age Designs

Iron Age Designs has been around for a few years in the designer cast iron grate market. Their 12” x 12” catch basin grating options, designed to fit the NDS 1200 basin series, are top notch.  Coincidently (or by default), they also fit the ADS and Old Castle 12” catch basin product lines. These grates are strong enough to use in a driveway drainage application. They will easily support the weight of a delivery truck or car. Expect to pay over $100 dollars for one of these grates. Also, expect years of enjoyment from one of these grates being an heirloom in your outdoor living space.

Patio and Driveway Drainage Solutions – Low Profile Drain (Part 1)

Just about any place in need of a drainage point can use catch basins (or one of their many variations) to evacuate water. Homeowners can use catch basins for driveway drainage, pools, patio point drains and landscape area drains. And, the installation techniques employed will be as diverse as the application.

buy plastic grates online, buy 5" plastic grates, buy nds drains online, 5 inch pro series buy nowAn interesting variation of a catch basin is the low profile adapter. This is truncated, or shallow housing that is designed to accept a standard 12” x 12” catch basin grate and allows for direct connection to a vertical drainage pipe. These drains are similar in character to single point floor drains used inside the home, but without the flanges and waterproofing features. They have no reservoir to collect debris from the run-off water. They simply fit on top of the vertical 3”, 4” or 6” PVC drain pipe that is part of the drainage system (shown below without grating).

NDS Low Profile Adapter on Pipe, nds, low profile drain, shallow catch basin

There are at least three companies that manufacture a 12” x 12” low profile adapter: ADS (American Drainage Systems), NDS (National Diversified Sales) and Old Castle (Formerly Carson Industries). All three companies have slightly differing product designs while maintaining the ability to accept a 12” x 12” x 1.25” thick grating. Two of these are compared below. At first glance, the ADS and NDS low profile adapters seem the same. And, from a strictly drainage functionality aspect, they are.

Low Profile Adapter Comparison, nds low profile, ads low profile adapter, ads catch basin, plastic drainage system

Both products have a similar dimensioned housing to carry the grate. The grates used in each drain are actually interchangeable. Each product requires a twist-in adapter (3 – 4” and 6”) to interface with the drainage pipe. Both are black colored. Even the company acronyms are close. ADS? NDS? What’s the difference?

There are a few subtle differences between the two low profile adapters that become apparent when you hold them. The ADS product is made from Polyethylene (PE) whereas NDS makes their product from Polyvinyl Chloride (PVC). Parts made from polyethylene are a little more flexible and durable than PVC parts. PVC is easier to crack or break, especially in cold temperatures. But this characteristic may not have any bearing on longevity or performance, especially when the drain is installed in concrete.

The flip-side of that material analogy is that PVC, being a slightly stiffer material, gives the impression that the NDS product is a well designed, cleaner fitting drain body. Of course, the ADS drain body has the same design quality as the NDS product. However, the flexibility and feel of polyethylene may give an impression of it being an inferior product. This is certainly not the case, however.

ADS, NDS, pipe adapter, pipe fitting, low profile adapter, low profile drain, shallow residential drain

The pipe adapter is an important part of the low profile adapter. It is the link between the grate housing and the drain pipe. As we all know, there are many drain pipes that can be used for an outdoors application, depending on the amount of water anticipated. Generally, 3” and 4” diameter pipes will handle the flow of water experienced in a residential setting. The two adapters, shown above, are designed to attach to both pipe sizes, both PVC and corrugated PE. Both adapters work well with their respective drain housing. For higher volume flow applications, pipe adapters for 6” diameter pipes are available from both manufacturers.

When installed in a patio or driveway, the low profile drain will be hidden from sight and the only thing visible is the top grating. There are a number of products available made to fit both of these housings. Each manufacturer has their own set of standard plastic and cast iron slotted grates, which are affordable, functional and diverse. We will discuss more decorative grating options in our follow-up blog.

The Next Generation Basin by NDS

Over the past couple years we have posted several articles discussing catch basins and catch basin installation. More specifically, we have found ourselves focusing on the broad selection of catch basin products for yard and downspout drainage manufactured by National Diversified Sales (NDS).

buy plastic grates online, buy 5" plastic grates, buy nds drains online, 5 inch pro series buy now

This article is devoted to one of my favorite NDS catch basin products called the Next Generation Basin, or 1200 NGB. The 1200 NGB is a unique 12” x 12” catch basin that allows you to adjust the invert elevations of the catch basin without changing elevation at grade (at the grating). No other residential grade catch basin has this feature!

next generation basin, nds, plastic drain

Take a look at the 1200 NGB catch basin kit (above), which contains two open adjustable wall panels. The round openings in the basin’s wall panels are specifically designed to accept one of NDS’s universal outlets.  So, not only are the inverts for the 1200 NGB adjustable, but it can fit a variety of piping options, too.  In the photo below, a 1243 pipe adapter is shown alongside a panel wall.

If only one outlet is needed for the catch basin, the 1266 plug adapter can be inserted to seal up the wall.  NDS also offers a solid wall panel (or plug side) can be inserted to close the open side (see photo below).  Still, the plug side does offer a knock-out for a pipe adapter if you later change your mind about having an outlet at that location.

plastic trench drain, catch basin system, residential trench drain

The 1200 NGB system was developed to make catch basin installation easier and more convenient. You can see in the photo below that it has three snap off side-outlet options, each changing the slope of drainage slightly. The lowest setting eliminates most sitting water from the basin, leaving less room for a sump to catch debris but draining the quickest. The center setting is the standard and connects with the middle of the catch basin. The highest setting gives the catch basin more elevation for drainage that needs to travel a longer distance. Depending on the situation, each of these outlets can be just what is needed to complete the job.

The 1200 NGB basin also gives you options in bottom discharging. In the bottom of every basin is an adapter knock-out (similar to the plug side knock-out), which can attach to solid a PVC pipe that feeds off your drainage system.  By attaching the bottom outlet to a perforated pipe, you can create a leaching system uses storm water to recharge the ground water.   Small “weep hole” knock-outs are also located in the bottom corners of the catch basin for those who are just trying to rid the basin of standing water.

The fourth option offered by the Next Generation Catch Basin is a total bottom cut-out, which allows the maximum amount of storm water to be put back into the ground. As the ground becomes saturated, excess water reaches the pipe elevation and is taken away in the drainage system. Though this option maximizes the water that remains on site – a popular choice among those interested in water sustainability – it is not the best option next to home foundations.

One of the best things about the 1200 NGB system, though, is the amount of grating options available for it. Standard plastic grating comes in 4 colors: black, sand, green and gray. Also, there are bronze, brass, galvanized steel and cast iron options. Below are examples of the  standard slotted cast iron grating (left) and the black plastic grating (right).

Other ornamental cast iron grating options are manufactured by Iron Age Designs are also available for this catch basin. Below are four gorgeous patterns that are popular in patio and downspout catch basins. Clockwise from the upper left, the pattern names are Interlaken, Locust, Sun and Oblio.

These grates fit perfectly with the 1200 NGB.  What makes the designs so fantastic is how each one incorporates a different image of nature into what would otherwise be a simple work of cast iron. The Interlaken Grate on the top left has a beautiful yet strict design; it must be a representation of the solid form of earth.  On the top right, the Locust Grate provides a breezier feel; the leaf patterns soften the harshness of the material until it seems to flow.  With the grate pictured on the bottom left, the Oblio Grate, you can get a sense of water in the concentric circles; the grate is reflecting the distorted surface of water during a rain.   At the bottom right, the Sun Grate exudes warmth and intensity; the sun seems to pop out of the plain background of circles.   Consider painting this grate in bright colors prior to installation.

Mini Channel’s Decorative Grating Options

National Diversified Sales (NDS) is a plastic trench drain manufacturer based out of California.  They have a fantastic selection of plastic trench drain systems that are used in residential and commercial applications.  The 3 inch-wide Mini Channel is popular because its honeycomb design and inexpensive price appeals to contractors and homeowners.  However, a big part of the drainage system’s popularity comes from the number of complementary grating options offered.

The standard grate offered with the Mini Channel is still a 3 foot long plastic grate, which is offered in six colors (gray, white, green, black, red, and sand).  Gray was the go-to color in the past, but customers are now branching out for colors that blend with the hardscaping; sand and white plastic grates, especially, are gaining popularity.

For those with a more discriminating taste, NDS offers two slotted brass grating options.   The 1 foot long brass grates come in a satin or polished finish. Besides being simple, shiny, and elegant, they contain chamfered holes for optional screw placement, which helps keep the grates secured in the channel.

Another option available for Mini Channel customers is decorative cast iron grates.  These aren’t the ordinary slotted grates of yester-year; the cast iron grating product lines below illustrate the beautiful side of a functional product that was previously considered a necessary – and ugly – evil by many homeowners.  (Note:  these grates are shown with a baked-on oil finish unless otherwise specified but come standard in an unfinished cast iron.)

Currently, five styles of cast iron grates work with NDS’ Mini Channel system: the Acanthus, Interlaken, Carbochon, Locust and the Minnione.  There are a few basic differences between these four Mini Channel grates.  The Interlaken is an intricate geometrical pattern while the Minnione has a flowing design.  The Locust pattern evokes the feel of leaves blowing in the wind.  Meanwhile, Carbochon’s open area is only accentuated by its bold pattern.

Style aside, the most noteworthy difference in the grates is length. The Interlaken (11″ long) is an inch shorter than the Minnione and Locust grates (12″ long).  The Carbochon (14” long) outdoes all three grates by inches.  I think the length of the grates is important because it determines what you can do with the design of the run.  Unfortunately, it is often overlooked during the planning stage and leads to extra work later on.

Another difference in the grates is how they fit into the Mini Channel.   Take a look at the photo above. Minnione, the thinnest grate, does not rest in the channel with the same depth that Interlaken, Locust and Carbochon do.  While the other grates are cast with tongues that fit snugly into the Mini Channel’s patented “flying buttress” lip, one gets the feeling that the Minnione sits on top of the drain rather than resting inside it.

The foundry uses cast iron as the standard material when making these decorative grates but also manufactures cast brass, bronze and aluminum grating for an additional cost. We should note that cast iron grates are uncoated (raw) and will form a rust coating over time.  The rusting process, when reproduced artificially to save time, is called a baked-on oil finish.  I find the resulting patina charming.

If your application doesn’t support this view, though, consider painting with an epoxy or powder coating. The powder coating process smoothes out the natural texture of the cast iron grates, giving them a softer, less metallic look.  You can really feel the difference between the painted and baked-on oil finishes; the process encased these grates in paint rather than changing their outer layers.

Let me just demonstrate the difference between the two available finishes in another way.  Look at the Interlaken grates shown below:  in terms of color, they are very similar.  But, if you look closer you can see the different shine, the thickly coated surface of the grate on the right.  It’s been powder coated.  The grate on the left, though, has a baked-on oil finish.   I’ll leave you to decide which one you like better.  For additional information on cast iron grating finishes, visit our “Cast Iron Finishing Options” blog.

Cost is all in a person’s perspective, especially when talking about trench drain products. A simple plastic grate that comes in six basic colors is available for a very low price per foot. NDS’ brass grate, a beautiful, no-hassle solution for those still worried about rust or decor, is the most expensive. The cast iron grates, which add style and variety, come for the more moderate price that falls somewhere in between and have beautiful finish options. They are the true extra mile, the art to efficiency, and are the balance if a cost-efficient and stylish grate is desired.
